BTW, the people behind Medium are Evan Williams and Biz Stone. Evan is the founder of Blogger, and Biz and Evan together were the founders of Twitter. They're very smart guys, obviously -- and Ev and I have co-created some open protocols, working at arm's length, but who cares. It worked. The Metaweblog API was a mashup, and has since become a standard. So when I make a proposal to make history together, it's not entirely like Don Quixote tilting at windmills.
